Abstract
The invention relates to a method for finishing a composite blade (10) of an aircraft turbomachine, this blade (10) comprising a blade (12) formed from a fiber preform embedded in a polymer matrix. According to the invention, the method comprises the steps of: a) weighing the blade (10) to determine its actual mass, b) determining a difference between a theoretical mass and its actual mass, and c) applying a coating to the blade (12), this coating having a volume which is a function of said difference and of a density of this coating after drying.
